Sofie, Its hard to know without looking at the idf file itself. Often times, this is caused by a wall whose normal vector is pointing the wrong way. The fix is simple: you simply have to select "reverse faces." The hard part is to figure out which wall is giving you trouble. Often times, you can look in the *.b17 for an adjacent wall whose adjacency is set to "undefined" and then start looking back in the idf file in Sketchup/Trnsys3D.
